fix azure storage account num exhausting issue

**What this PR does / why we need it**:
If customer is using the default storage class of azure-disk, create lots of azure disk pvs by using default storage class of azure-disk, the storage account num would be exhausted in the azure subscription. Change default `kind` value of azure disk storge class from `Dedicated` to `Shared`, which means only a few storage accounts would be created even there are even hundreds of azure disk PVs.

**Which issue this PR fixes**:
fixes #54669
fix storage account num exhausting issue when lots of azure disk pvs are created by using the default storage class of azure-disk

**Special notes for your reviewer**:

RBD Plugin: Implement Attacher/Detacher interfaces.

**What this PR does / why we need it**:

This PR continues @rootfs 's work in #33660. It implements volume.Attacher/Volume.Detacher interfaces to resolve RBD image locking and makes RBD plugin more robust.

Summary of interfaces and what they do for RBD plugin:

- Attacher.Attach(): does nothing
- Attacher.VolumesAreAttached(): method to query volume attach status
- Attacher.GetDeviceMountPath(): method to get device mount path 
- Attacher.WaitForAttach(): kubelet maps the image on the node (and lock the image if needed)
- Attacher.MountDevice(): kubelet mounts device at the device mount path
- Detacher.UnmountDevice: kubelet unmounts device from the device mount path (currently, we need to unmaps image from the node here) (and unlock the image if needed)
- Detacher.Detach(): does nothing

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

fixes #50142.

**Special notes for your reviewer**:

RBD changes:

  1) Modify rbdPlugin to implement volume.AttachableVolumePlugin interface.
  2) Add rbdAttacher/rbdDetacher structs to implement
  volume.Attacher/Detacher interfaces.
  3) Add mount.SafeFormatAndMount/mount.Exec fields to rbdPlugin, and setup them in
  rbdPlugin.Init for later uses. Attacher/Mounter/Unmounter/Detacher
  reference rbdPlugin to use mounter and exec. This simplifies
  code.
  4) Add testcase struct to abstract RBD Plugin test case, etc.
  5) Add newRBD constructor to unify rbd struct initialization.

Non-RBD changes:

  1) Fix FakeMounter.IsLikelyNotMountPoint to return ErrNotExist if the
  directory does not exist. Mounter.IsLikelyNotMountPoint interface
  requires this, and RBD plugin depends on it.
  2) ~~Extend Detacher.Detach method to pass `*volume.Spec`, RBD plugin
  needs it to detach device from the node.~~
  3) ~~Extend Volume.Spec struct to include namespace string, RBD Plugin needs
  it to locate objects (e.g. secrets) in Pod's namespace.~~
  4) ~~Update RABC bootstrap policy to allow
  `system:controller:attachdetach-controller` cluster role to get
  Secrets object. RBD attach/detach needs to access secrets object in
  Pod's namespace.~~

**What this PR does / why we need it**:

Remove federation

This PR removes the federation codebase and associated tooling from the tree.

The first commit just removes the `federation` path and should be uncontroversial.  The second commit removes references and associated tooling and suggests careful review.

Requirements for merge:

- [x] Bazel jobs no longer hard-code federation as a target ([test infra #4983](https://github.com/kubernetes/test-infra/pull/4983))
- [x] `federation-e2e` jobs are not run by default for k/k

**Release note**:

```release-note
Development of Kubernetes Federation has moved to github.com/kubernetes/federation.  This move out of tree also means that Federation will begin releasing separately from Kubernetes.  The impact of this is Federation-specific behavior will no longer be included in kubectl, kubefed will no longer be released as part of Kubernetes, and the Federation servers will no longer be included in the hyperkube binary and image.

Fallback to internal addrs in e2e tests when no external addrs available

This change modifies the way that config.NodeIP is selected at the
start of e2e Networking tests such that if no external addresses are
available from the cloud provider (e.g. either no cloud provider being
used [baremetal or VMs], or the provider doesn't have external IPs
configured), then one of the internal addresses is used.

Without this change, the e2e service-related Networking tests will always
panic when config.ExternalAddrs[0] is accessed and the slice is empty.

This change eliminates the panic, and in some setups, the fallback choice
of using an internal address will provide the necessary connectivity
for the e2e Networking tests to access each node.

 Removed containers are not always waiting

fixes #54499 
The issue was that a container that is removed (during pod deletion, for example), is assumed to be in a "waiting" state.
Instead, we should use the previous container state.
Fetching the most recent status is required to ensure that we accurately reflect the previous state.  The status attached to a pod object is often stale.

I verified this by looking through the kubelet logs during a deletion, and verifying that the status updates do not transition from terminated -> pending.

Update to latest kube-openapi and kazel

- update vendored kube-openapi to include https://github.com/kubernetes/kube-openapi/pull/14
 - update hash of repo infra used for bazel generation so kazel includes https://github.com/kubernetes/repo-infra/pull/48

This is the final step in enabling federation to generate openapi code for itself and vendored kube (#54335).
